Development of new healthy products: fresh processed pomegranate seed.  The pomegranates have been cultivated over the whole Mediterranean region since ancient times.This fruit presents unique organoleptic and nutritional properties which have been always appreciated.However, its consumption is still reduced due to the difficulty in obtaining the delicious arils.Therefore, the enormous potential of this cultivar in the Mediterranean area has not been completely achieved jet.A possible answer could be the development of a new product: minimally fresh processed pomegranate arils.The objective of the present work was to study the different behaviour of two clones of the Mollar cultivars (Mollar of Elche and Mollar of Orihuela), their suitability to fresh processing as well as to determine the best gas composition to keep longer the fresh properties of this product.

Once the arils of the pomegranates were extracted from the fruit, they were fresh processed (washes, rinsed, dried and packaged) and stored at 5 °C for 11 days.125 g of pomegranate arills were package in polyethylene baskets and sealed with bioriented polypropylene of 40 mm (PPB40) to generate a passive and an active modified atmosphere (MA) inside the package.The control was obtained by storing the product in a macro perforated film.Several analyser were carried out during the shelf life of the product: microbial count, sensorial quality and gas composition inside the baskets.

Differences between clones were found in the atmospheric composition inside the baskets when active MA was used.It seems that Mollar of Orihuela has higher respiration rate when stored in active MA.When the microbial growth among the two MA and the control was compared a reduction was observed by using both MA.The sensory panel determined a shelf life of 9 days for this product.In their opinion the product stored under passive MA obtained the best scores for both clones.
